Dual 1 Form A Solid-State Relay (Normally Open)
DESCRIPTION
The LH1532 dual 1 Form A relays are SPST normally open
switches that can replace electromechanical relays in many
applications. They are constructed using a GaAIAs LED for
actuation control and MOSFET switches for the output. In
addition, the LH1532 SSRs employ current-limiting circuitry
to provide overvoltage protection.
FEATURES
• Dual channel
• Current limit protection
• Isolation test voltage 5300 VRMS
• Typical RON 22 Ω
• Load voltage 350 V
• Clean bounce free switching
• Low power consumption
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• General telecom switching
• Security equipment
• Instrumentation
• Industrial controls
AGENCY APPROVALS
• UL1577, file no. E52744

Note
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability
Note
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluations. Typical values are for information only and are not part of the testing requirements
